GATE.

application inea July 27,

This invention relates to an improved gate, and it has more particular reference to one Which is particulznfly, but not nl-xcessarlly, `designed Jfor use in association with `a t'arni fence, the' saine beingadapted to' occupy `the `ol'lening now ordinarily occupied by the 'common forms of gates. f

rlhe i-nventioii has more particular reference to a structure of this kind' wherein the gate prop'eris mounted for vertical swinging upon a horizontal axis, the same including plates "forming rails or tracks over Whichthe 'Wheels ci' a vehicle may pass when the gate is swung doivn to lie upo'nthe` ground;

One feature ofthe invention is theifiovel traine 'fo`i""13i\fotzil mounting, together With the parts cooperating `thereivith` to form an y etlicient closure and to provide the aforesaid tracks.

Another feature ot construction is the mounting traine Work which is properly bra-ced to render it sturdy.

A further feature results from the provision ol counter-weights Which are connected with flexible elements in turn connected Iwith the gate for normally maintaining the gate in a vertical closing position and tor automatically returning it to such position atter it has been pushed down by the vehicle and the latter has passed over it.

Other features and advantages of the invent-ion will become apparent from the following description and drawings.

.ln the accompanying drawings Figure 1 is a 'liront elevation ot' a gate structure constructed in accordance with the present invention,

Fig. 2 is a. side view otl the same,

Fig. 3 is a top plan view, and

Fig. 4 is a perspective view of one of the details.

1n the drawings, the reference character 1 designates the base portion of the supporting frame work, and the reference character 2 designates vertical standards which' rise therefrom. The upper ends of the standards are biturcated and the turcations are bent upon themselves to provide bearings 3 for pintles of a pulley 4. Mounted on the inner side of the standard just below the pulley in each instance, is a boxing 5 which serves to accommodate a pair of smaller pulleys 6 (see Fig. 8), serving as `guides for a flexible element 7, which is trained over the larger pulley 4. It will be noticed that 192'6. serial No. 125,'22.

the pulleys 4 are4 disposed at right angles to Alt thistime",r attention n'iight be directed to bun'ip'er springs 10 which surround the cords 'i and cooperate lwith Athe Weights 8.5 r

Considerii'i'gnoiv the gate, per se,` it vwill be seen that this comprises va' s'uhs'tantially'U- shaped trame 11,.:1 cross piece 12 connected `to the arfn'r's thereon, vertical pieces 13, and

a secondcross piece 14. `The bightportion ot the trainers rotatably intinnted in bear-` ing b'racketsl' attached to" the central portion 'ot the base p'laterl.

Attentijrnris nowdirected to such snppl'emental details as brace `rods 1G connected with the" upper portionof the uprights or standards and with the end portions of angle irons `17. Additional braces 18 are employed and provided `at their lower ends with eyes 19 adapted to be suitably secured to the ground adj acentthe structure. Moreover, lubricating devices 2O are employed Wherever necessary to facilitate tree run-` ning ot the pulleys. Stops 21 cooperate with the pulleys 4 and the coiled springs 10. Moreover, if desired, a suitable sheet metal housing 2:2 may be employed to enclose the parts as shown in dotted lines in Fig. 1. Then too, small guide blocks of suitable inaterial represented by the reference character 23 are preferably employed, the saine beingv wheels will substantially engage the cent-ral upper portion of theV parts 13 which are then in vertical position. Then by 'forcing against the gate, it may be rocked down upon the ground as shown in dotted lines in Fig. 3. The guide blocks 28 will aid in approaching the gate and will also aid in leav ing the rails as is obvious from the represen tation made in Fig. 3.

The advantage of the structure is that it obviates the necessity of getting out ott the vehicle and opening t-he gate in the usual manner. The operator simply runs against the gate or forces it down to the ground and then runs over it. Immediately upon passage of the vehicle thereover, the counterbalance Weights and flexible elements serve to swing it rapidly back to closing p oslthe pasture Will not escape. i

tion in order that animals and the like in The parts are usually so balanced that" they prevent easy opening of the gate by the mere pressure of an aniinalagainst the saine;

l; In a structure of the, class described,`

a substantially U-shaped supporting frame, supporting means `forthe frame, a closure, said closure comprising a substantially U- shaped frame, a: cross piece connected With the arms of the closure frame, Vertical plates connected with the central portions of said closureframe andWith saidcross piece, and disposed at right angles thereto, said plates being adapted to function as tracks, and bearing brackets attached to the bight portion oi the first named trame, the said biwht portion "of the closure frame being rockatloly connected with said brackets and yieldable Umeans for maintaining said gate normally in a closed position.

2. ln a structure ot' the class described, ay

substantially U-shaped supporting frame, supporting means i'or `the trame, a closure, said closure comprising a. substantially U- shaped fliranie, a cross piece connected with,

the arms ol the closure `l"ran1e, vertical plates connected with the central portion ol' said closureframe and with said cross piece and disposed at right angles thc-neto` said plates being adapted to function as tracks, and

bearing-brackets attached to thebight por-` tionsof the iii-st named frame, the said hight a portion of the closure frame being roelmhly` connected with said brackets, pulleys at the upper ends of the `Vertical portions of the supporting frame, flexible elements connected With the arms ogt' the closure frame and passing over said pulleysand downwardly, and counter-balancing weights connected to the lower free ends of said flexible elements.

In testimony whereof I aiiix my signature.
